HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-
draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
Stanley Hydraulic Tools. They are:
Certified non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified non-
conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforce-
ment, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near
electrical conductors.
Fabric-braided (not certified or labeled non-conductive) — constructed of thermoplastic or synthetic rubber in-
ner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certified non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from Stanley Hydraulic
Tools. DO NOT REMOVE THESE TAGS.
If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be
obtained from your Stanley Distributor.

OPERATION
At times it may be neccessary to reset the controller. This
could happen if a fault occurs in the controller. For ex-
ample, excessive engine speed. If a fault does occur the
power unit will return to an idle and the operator will have
no control of the unit. To reset the controller, simply turn off
the power unit and restart it.
CONTROLS
This unit is equipped with an advanced proportional engine
control system. It provides a means of controlling engine
speed by adjusting the fuel control lever with an actuator.
The Power Unit provides one circuit, with an oil flow of 5
gpm/19 lpm up to 2000 psi/140 bar or 8 gpm/30 lpm up
to 2000 psi/140 bar with a factory-programmed electronic
governed engine throttle.
STARTUP
Before starting the engine make sure the flow selector
throttle control
switch
switch is in the OFF position.
Note:
flow selector
switch
The power unit will not start if the flow control switch is
not in the "OFF" position.
ignition switch
Pull choke knob out and move the Throttle Control Switch
to the auto-idle-off or the auto-idle-on position, whichever
mode of operation the operator prefers. Ensure the flow
selector switch is in the OFF position.
Figure 3. Control Panel
One hydraulic tool can be connected to the tool circuit.
The circuit is activated by turning the flow control switch to
either the 5 gpm/19 lpm or 8 gpm/30 lpm setting.
Turn the Ignition Switch to the START position. After the
engine starts, release the switch.
THROTTLE CONTROL
Gradually push in the choke knob as the engine begins to
idle smoothly.
The throttle control permits the operator to select one of 2
operating modes after the engine has warmed up. When
starting the engine, make sure the flow selector switch is
in the off position. The throttle control switch can be set in
either the auto-idle-on or auto-idle-off positions.
Allow the engine to warm up.
Connect hoses and the tool as desrcribed in this manual.
AUTO-ON
FOR 5 GPM OPERATION
When the throttle control switch is in the "AUTO-ON" posi-
tion, the oil flow is regulated automatically when the trigger
on the tool is activated. When the tool is not being used the
engine will return to idle automatically, after a 10 second
delay.
For 5 gpm operation, select mode of operation with the
Throttle Control switch, either auto-idle-on or the auto-idle-
off position. Move the flow selector switch to the 5 gpm
position.
This setting will produce 5 gpm/19 lpm or 8 gpm/30 lpm
depending on which postion the operator has selected with
the flow selector switch.
When finished operating the tool, move the flow selector
switch to the OFF position.
FOR 8 GPM OPERATION
AUTO-OFF
When the throttle control switch is in the "AUTO-OFF" posi-
tion, the engine speed is held to maintain 5 gpm/19 lpm or
8 gpm/30 lpm depending on which position the operator
has selected with the flow selector switch. When a tool is
not being used the engine will not return to idle until either
the flow selector switch is turned to the off position or the
throttle control switch is turned to auto-on.
For 8 gpm operation, select mode of operation with the
Throttle Control Switch, either auto-idle-on or the auto-idle-
off position. Move the flow selector switch to the 8 gpm
position.
When finished operating the tool, move the flow selector
switch to the OFF position.
Note:
It may be necessary to reset the Controller.

OPERATION
COLD WEATHER STARTUP
1. Use the procedures described under "STARTUP" and
then follow the procedure below.
2. Hydraulic fluids are thicker in cold weather. Therefore,
it is recommended that the engine be run at low idle long
enough to bring the fluid temperature up to a minimum of
50°F/10°C.
3. If the tools and tool hoses are cold, it is recommended
to allow hydraulic fluid to circulate through the tool hoses
until warm before using the tool.
SHUTDOWN
1. Ensure the flow selector switch in the OFF position
(center position).
2. Unless already at idle the power unit should return to
idle. This may take a few seconds for the unit to react due
to a built-in program delay.
3. Allow the engine to idle for approximately one minute
and move the Ignition Switch to the OFF position.

ROUTINE MAINTENANCE
ENGINE MAINTENANCE
• Change the hydraulic filter element every 200 hours of
operation. Change more often if cold, moist or dusty condi-
tions exist.
Follow the maintenance schedule and general mainte-
nance instructions in the engine maintenance and opera-
tion manual furnished with the power unit.
• Check oil cooler for debris. Remove debris with air pres-
sure.
SPARK PLUG
STORAGE
On power units equipped with Briggs & Stratton Engines,
ONLY Champion RC12YC or equivalent can be used.
• Clean the unit thoroughly before storage. Do not use
water pressure.
Incorrect type spark plugs can produce radio frequency
interference that will corrupt and damage the controller.
Failure to use the correct spark plug could result in a war-
ranty that will not be considered.
• Always store the unit in a clean and dry facility.
• If the unit will be stored for a prolonged period (over 30
days), add a fuel additive to the fuel tank to prevent the fuel
from gumming. Run engine for a short period to circulate
the additive.
HYDRAULIC SYSTEM MAINTENANCE
• Check hydraulic fluid level daily. Add fluid per specifica-
tions in this manual. (See "HYDRAULIC FLUID" under the
section titled "OPERATING INSTRUCTIONS".
• Replace crankcase oil with new oil.
• Remove condensed moisture from the hydraulic
fluid by pumping the hydraulic fluid into a 5 gal/20 l con-
tainer through the pressure hose. Make sure the engine is
at idle when performing this procedure. When the hydraulic
reservoir is empty turn the engine off immediately.
• Allow the fluid to sit long enough for the water to settle to
the bottom of the container. Slowly pour the fluid back into
the hydraulic tank, avoiding the water at the bottom of the
container.
• Each day, check hydraulic lines and fittings for leaks,
kinks, etc. Do not use your hand to perform this check.

Checking Performance Control™ (Electronic
Governor-Static Check)
To determine whether a governor problem is being caused
by the actuator or the control module, perform the following
static check exactly in order shown.
A pair of jumper wires and a known good 12-volt battery is
required.
1. Disconnect red and green wires from the control module
to actuator.
2. Attach jumper wires from battery to RED and GREEN
wires to actuator.
a. Attach 12 volt + (positive) to RED wire.
b. Attach 12 volt – (negative) to GREEN wire.
3. Actuator should move throttle lever to wide open position.

TESTING & TROUBLESHOOTING
9. At 2100-2200 psi/148-155 bar, the relief valve should
begin to open. The pressure at which the relief valve just
begins to open is commonly referred to as the "cracking
pressure". At the "cracking pressure," the flow rate should
start to drop because the relief valve is allowing fluid to by-
pass to the hydraulic reservoir. The "cracking pressure" is
preset at the factory and if it is not within the above range,
the relief valve must be re-set as follows:
GENERAL
Tests and adjustments should be performed periodically to
ensure the power unit is operating at maximum efficiency.
Stanley Circuit Tester (part number 04182) is recommend-
ed. This tester can be used to isolate problems in both the
engine and hydraulic system prior to any power unit disas-
sembly.
a. The relief valve is located on the right side of the unit just
behind the dash panel. It protrudes out from the manifold
assembly. Use a open end or box end wrench to loosen the
nut on the relief valve.
TESTING THE HYDRAULIC CIRCUIT
The following tests can be performed to ensure that the
hydraulic pump is supplying the correct flow and pressure
and that the system relief valve is operating properly.
b. Use an Allen wrench to adjust the relief valve. Turn
clockwise to raise the pressure and counterclockwise to
reduce the pressure.
During these tests, make sure the engine is warm and op-
erating smoothly. If test results are not as specified, refer to
the troubleshooting table in this section for possible causes.
c. Tighten the nut and retest.
Testing The 5 gpm htma type I circuit
or the 8 gpm type II circuit
To test the circuit, proceed as follows:
1. Set the flow selector switch to the OFF (center) position.
2. Set the throttle control switch to AUTO-OFF position.
3. Connect the Stanley Circuit Tester across two hose ends
(where the tool would normally be connected).
4. Fully open the tester restrictor valve (counterclockwise).
5. Start the engine and allow it to run until warm.
6. Switch the flow selector switch to 5 or 8 gpm depending
on which flow you are testing.
7. With the engine at the programed speed, the test flow
gauge should read 4-6 gpm/15-23 lpm or 7-9 gpm/26.5-34
lpm.
8. Slowly turn the restrictor valve clockwise while watch-
ing the pressure gauge. The flow rate should stay at 4-6
gpm/15-23 lpm or 7-9 gpm/26.5-34 lpm as the pressure
gauge reaches 2100-2200 psi/148-155 bar.

FUEL TANK & CAP
NOTE: When ordering a fuel tank (item
37) or fuel tank cap (item 35) DO NOT
MIX OLD STYLE TANK AND CAP
WITH NEW STYLE TANK AND CAP.
If you have a power unit and it was pur-
chased prior to 2011 and need to re-
place the fuel tank or fuel tank cap, you
must purchase the same tank and cap
that came with your unit.
For example if you have a power unit
prior to 2011 do not purchase a new
style fuel tank, your engine will not be
equipped with a fuel vapor fitting.
The old style fuel cap is a vented cap,
while the new style fuel cap is not a
vented cap and venting is achieved thru
the vapor line.
The old style fuel tank has only one fuel
line coming from the tank to the engine.
The new style fuel tank has two lines
coming from the fuel tank to the engine,
one is the fuel line and the other is a fuel
vapor line.
